Clustering geofence-based alerts for mobile devices
A geofence management system obtains location data for points of interest. The geofence management system determines, at the option of the user, the location of a user mobile computing device relative to specific points of interest and alerts the user when the user nears the points of interest. The geofence management system, however, determines relationships among the identified points of interest, and associates or “clusters” the points of interest together based on the determined relationships. Rather than establishing separate geofences for multiple points of interest, and then alerting the user each time the user's mobile device enters each geofence boundary, the geofence management system establishes a single geofence boundary for the associated points of interest. When the user's mobile device enters the clustered geofence boundary, the geofence management system notifies the user device to alert the user of the entrance event. The user then receives the clustered, geofence-based alert. |

A driver circuit of a display device, which includes TFTs of a single conductivity type and outputs an output signal with normal amplitude. A pulse is inputted to TFTs 101 and 104 to turn ON the TFTs and a potential of a node α is raised. When the potential of the node α reaches (VDD−VthN), the node α becomes in a floating state. Accordingly, a TFT 105 is turned ON and a potential of an output node is raised as a clock signal becomes High level. On the other hand, a potential of a gate electrode of the TFT 105 is further raised due to an operation of a capacitance means 107 as the potential of the output node is raised, so that the potential of the gate electrode of the TFT 105 becomes higher than (VDD+VthN).

An output at the subsequent stage is then inputted to a TFT 103 to turn the TFT 103 ON, while the potential of the node α of TFTs 102 and 106 is dropped to turn the TFT 105 OFF. As a result, the potential of the output node becomes Low level. |

Announcing a communication session within a wireless communications system
An access network (AN) receives a call announcement message for transmission to an access terminal (AT). The AN initiates, in response to the received call announcement message, a physical-layer synchronization procedure for at least one channel between the AN and the AT, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state. The AN performs the initiation by sending a message to the AT. In response to the message, the AT monitors a downlink channel for receipt of the call announcement message. The AN then transmits the call announcement message on the downlink channel to the access terminal, and the AT receives the call announcement message due to the monitoring. The call announcement message is transmitted either (i) before the physical layer synchronization procedure completes or (ii) before a transmission of a reconfiguration complete message indicating completion of dedicated channel state transition. |

System and method for a virtual reference interferometer
An interferometer generates interference between two (or more) waves that have traveled separate paths so as to measure a quantity of difference between these paths. One of these paths, the reference path, is usually one with well known spatial and material properties (such as free 5 space). The other path(s) is(are) the test path(s). The main difficulties in interferometry stem from the production and operation of this physical reference path. The present invention solves this problem by replacing the physical reference path with a virtual one. This is done by suitable operation on the physically generated interference pattern of an unreferenced interferometer with a virtually generated sinusoid of frequency corresponding to the desired reference path length. The result is a new form of interferometer called a Virtual Reference Interferometer. |

A conferencing system includes a user interface generator, a live conference processing module, and a replay processing module. The user interface generator is configured to generate a user interface that includes a replay control panel and one or more output panels. The live conference processing module is configured to extract information included in received conferencing data that is associated with one or more conferencing modalities, and to display the information in the one or more output panels in a live manner (e.g., as a live conference). The replay processing module is configured to enable information associated with the one or more conferencing modalities corresponding to a time of the conference session prior to live to be presented at a desired rate, possibly different from the real-time rate, if a replay mode is selected in the replay control panel. |

Image forming apparatus with a control unit for controlling light intensity of a beam used to scan a photoreceptor
An image forming apparatus having: a light source that emits a beam; a photoreceptor that is scanned with the beam to obtain an electrostatic latent image thereon; and a control unit that determines a light intensity of the beam to be emitted for formation of a pixel, based on a data value for the pixel in image data and data values for its surrounding pixels. |
